Jennifer Aniston Buys SICKEST Mansion Ever!!!

Jennifer Aniston is about to become the proud owner of an estate you will never be able to afford ... TMZ has learned.

Sources tells us ... Jennifer has purchased an 8,500 square foot mansion in Bel Air. The asking price was $24 million, but we're told Jennifer got it for a bargain -- only $21 mil.

The Mid Century house has 4 bedrooms and 6 bathrooms and unobstructed city and ocean views. The estate is just shy of 2 acres ... and in Bel Air, that's HUGE. And get this ... it even has a vineyard!

Jennifer's realtor is Jade Mills from Coldwell Banker in Bev Hills. Mills is having a good month. She repped Avril Lavigne, who sold her $8.5 million mansion to L.A. Clippers star Chris Paul last week.

We're told Jennifer will officially get the title to her new pad tomorrow.
